Chubb 3G110Chubb 3G110 A big thank you goes out to Simon Owen for providing this informative guide on understanding the Chubb 3G110. I have known Simon a long time and he understands this lock as well as anyone I know. Hopefully this information will help those who are experiencing problems in opening the lock.

This guide has been written to enable users of the Safeventures 110 pin and cam system to better understand a technique for opening these locks.

The technique relies on you identifying the difference between pattern 2 and pattern 3 detainers, once identified it is much easier to find a true gate.

Often too much rotational force results in ‘false binds’ which cause false pin moves which will result in the lock not opening. Fractional movement of the cam is all that is required
If you follow the process of identifying the lever pattern first and sticking rigidly to this system Chubb 110 lock opening should become much easier.

A detailed knowledge of the working parts of a lock enables you to understand better what is going on during the decoding process



Fig 1: Chubb 110 internal named parts

The bolt thrower rotates and lifts the vertical linkage (secondary gated lever). This allows a pressed stump to clear the gate of the bolt.
Only when the correct key is inserted will the detainers line up allowing the bolt stump which is part of the detent arm to move which will allow this lifting process. A full description of history and operation of the lock can be found in High Security mechanical locks by Graham Pulford.



Fig 2: Key reference

During the decode of most standard 5 lever mortice locks positions 1 and 3 (1 being closest to the bolt) are the same for reasons of key symmetry. This is often referred to ‘ABA pattern’ which assists when decoding.

Standard 5 lever mortices normally have seven cuts, the chubb 110 has nine.

Although the key is symmetrical we have no ABA pattern in the decode so the detainers are referred to as A to E.



Fig 3: Cut heights

1: 14.0mm
2: 13.4mm
3: 12.5mm
4: 11.7mm
5: 11.0mm
6: 10.3mm
7: 9.5mm
8: 8.7mm
9: 8.0mm

Series contains 9 differs, 1 being highest cut 9 being lowest. The scale is available from Souber tools. Be aware of the levers not directly relating to the factory specified height. This is a slight fault in the manufacturing process which does not effect the correct key (as the detainers are vertically milled whilst seated on the key) but it can give false decode readings ending in an unsuccessful entry.



Fig 4: Chubb 110 pin and cam

This is a modified 110 pin and cam decoder. In operation it is the same tool however the tip has been machined to a theoretical 10 cut to allow for 9 pin tests.

The  system.

The decode system works on the principle of identifying the pattern 2 and pattern 3 detainers. Called as such due to having 2 or 3 shallow false gates machined into the fence of the detainer. These false gates can be detected and will interact with each pin during the decode process.

Determining the difference between P2 P3 is described fully and is fairly straight forward. It is advised to project this noting the differences whilst decoding and practice identifying P2 and P3 detainers.



How the system works



Close inspection of the pictures on the previous pages show the interaction of the bolt stump and the lever. Once you can distinguish which pattern of lever you are working it becomes simple to identify when the system changes.
Every pin height interacts in a different way on the P2 and P3 detainers and when you get a change it is very obvious.
When the reading changes it is safe to say you are in the true gate.

In the above case the detainer will have fractional movement followed by bind upon lift. The reverse, a bind followed by free moving cam can fool the user into thinking they are in a true gate.

Locate your most binding detainer and only drop a pin if it binds at TDC (top dead center). If it moves even fractionally, do not drop. It will either be correct or it will bind the closer you get to decoding the lock.

User should construct a chart showing interactions at all heights between the detainer and bolt stump. Incorporate it into the pin box helps you to work through the system. An example chart is contained in the document.

The biggest common mistake is to drop a number 1 pin when it is in fact supporting a number 1differ detainer.
This happens because of the production of the detainers sometimes causes a slight increase in the height – a 1-1/4 height. A cut key to 1 height will open this fine, a fractional lift with a number 1 pin will cause the lever to bind, giving a false reading. You will continue to test through the pins without any success.

The rear cam indicator should be moved no more than about 3mm in one direction only (user choice).
If the cam moves (even minutely) leave that position alone!
Only move down binding levers. If no lever binds perform a 9’s test

Do not use too much force, this will possibly damage the cam which will provide false readings and you will damage your pins.



A small line drawn onto the rear of the body will ensure that the cam is lined up correctly prior to insertion. This must be done to avoid false readings.

The tool should be regularly serviced. Strip the tool completely clean and polish all internal components. This keeps the operation smooth as it is important in distinguishing the difference in the readings.

Round off the pins and ensure that they are not bent, they will stick in the tip pin chambers and again give false readings. A small quantity of grease applied to the pins prevents any loss and assists in smooth operation

The ‘Nines test’

The “nines test’ is merely the consecutive removal of pins.
You have tested all positions with no bind.
Remove position A detainer and re-test all other detainers B through to E. If when one pin is removed another position then binds it is a very good indication that the removed pin is a 9. It cannot be an anti-pick notch as they are not that high up on the fence of the lever.

If a single nines test fails to identify a binding lever it can be assumed that more than one nine is present. Chubb do not use identical levers next to each other therefore pin removal sequence is obvious. Positions B and D are tested first followed by positions A, C and E.
If a nines test fails to work the system has not been correctly followed and it is suspected that a pin has been dropped wrongly. The user must re-start the process.


Old style detainers

This system was developed to assist in opening the new style detainers because although the antipick notches are very shallow they are designed specifically to thwart the use of decoding tools.
The old style detainers were either totally blank or had antipick notches 1 height above and below the true gate.
The notches are approximately 1/3rd of the depth of the true gate and exactly the thickness of the bolt stump

1    Notch above gate and in ‘toe’
2    Notch above gate and in ‘toe’
3    Notch above and below gate
4    Notch above and below gate
5    Notch above and below gate
6    Notch above and below gate
7    Notch above and below gate
8    Notch below gate, slight notch above gate
9    Notch below gate

NEW PIN & LIFT TOOLS
 
NEW PIN & LIFT TOOLS We now have the pin and lift tools for Chubb 3G114, 3G110 and Legge curtained lever locks.For the past 20 years we have used pin and cam technology against these locks whilst using the far more sensitive pin and lift technology against high security safe locks. The systems are very similar in their application but pin and lift is a more successful and user friendly approach to the problem.The main reason for change is defeat of the Chubb 110. This is an extremely good quality lock with over 23000 key code possibilities.Over the years myself and others have struggled on this lock due to lack of feel and what is known as lever slip.I have recently tested pin and lift against the problem and started to supply a few customers on a trial basis. Below is some feedback that has influenced the decision to make change.\" I would like to give you some feedback having used the new Chubb 110 pin and cam, or as I refer to it, pin and plunge.

Basic Safe Opening Course
 
Basic Safe Opening Course Dates for future courses in 2014 will be announced soon Martin Newton Basic Safe TrainingLIMITED to 4 PLACES Safe & vault opening is a vast subject, Martin\'s personal knowledge and database has developed over a twenty year period and he is still learning.Our approach to this subject is to divide it into sub categories. The criteria for doing this is popularity of container and degree of difficulty to open. The majority of safes manufactured and purchased  can be described as containers with a cash value of less than £10,000.00. This cash value is allocated by the Association of British Insurance Surveyors.Our Basic Safe Opening course centers around safes that are 10k rated and less. This includes Hotel Safes, Domestic Safes, light commercial safes floor safes and wall safes.By definition these containers are usually constructed to a fairly decent physical standard and are often secured in position i.e., bolted to the floor or wall.  Open access can be secured by m... read more

Congratulations Ron Snively
 
Congratulations Ron Snively Below is an article concerning my good friend and former S.A.V.T.A. president Ron Snively. A very professional job, well done Ron.Police in Conyers, GA, near Atlanta, are investigatisng a case of a toddler who walked into a bank vault on Friday, just as the timers activated, locking the little girl inside the bank vault. A technician was rushed to the bank, escorted by the police at a 90-mile-per-hour clip, to drill out the lock and rescue the child.Apparently, the little girl and her mother were visiting the child’s grandmother, who is an employee at the Wells Fargo branch at GA Highway 138 and GA Highway 20, where the incident occurred. Deputy Chief Mike Lee of the Rockdale County Fire Department indicated that the little girl was freed from the vault at approximately 9 p.m., after three hours inside, “crying a little bit, but doing well,” reported television station 11Alive in Atlanta.The incident occurred after the bank had actually closed, and customers had left the bank.

A few words on combination lock manipulation by Mark Bates
 
A few words on combination lock manipulation by Mark Bates During the past five years I have had the good fortune to spend time opening safes with a close friend from across the Atlantic, Mark Bates. Mark is the owner of MBA USA Inc, a locksmith and safe technician tool supply and training company. During visits to the U.K. I have witnessed Mark manipulate several combination locks. The time taken has varied from30 minutes to 5 hours and there was only one occasion that Mark was defeated by the lock. All of the above has led to many conversations regarding, what I would describe, as the subtleties of manipulation. It has been during these discussions that I have come to realise that Mark Bates knows a LOT about manipulation.I have asked him to try and explain  a little of that knowledge here. MARKS RESPONSEI have been asked to say a few words about combination lock manipulation. This is more difficult than might be imagined, as manipulation is the act of doing…of being fully absorbed in the present. It is not a thing that can be easily ... read more
 
Update of Ford Tibbe Instructions
 
Update of Ford Tibbe Instructions The ford Tibbe lock is a rotary disc mechanism.  All of the discs need to be rotated to a correct position before the side bar can locate into the true gates allowing the lock to open.There have been two designs of disc that have had distinct similarities. In both designs there has always been one true gate and two false gates. In the first ,early, design the false gates were shallow gates that imitated the true gates. In the second and current design the false gates are notches cut into the disc. The notches are wide enough to allow the side bar to catch into them when picking.                                  PickThe Tibbe pick comes with a central wire that runs through the tool. This wire is required to achieve tension in order to pick the early locks. Tension is achieved by putting the wire to the back of the lock... read more
 
So you want to get into safes. By Martin Newton
 
So you want to get into safes. By Martin Newton I am constantly faced with enquiries from people wanting to start up in the safe trade, so I thought I would write this article to give an insight as to what is involved. About 10 days ago I had a call on my mobile phone, the caller asked if it were me by name and said he had been given my number by a mutual friend. He then said that he was standing in front of a ministry safe fitted with a MkIV Manifoil combination lock that would not open. For those that don’t know this job would fall into the category of high security. He wondered if I could give him a drill point. After asking a couple of questions I extracted from him that he had changed the combination on the lock less than 2 weeks ago and now it was not opening. The identity of the caller is still unknown to me, my advice to him, was to walk away from it and to advise the customer to call a professional safe engineer.This article is aimed at being informative and educational to those who are considering getting into safes in s... read more
 
The evolution of S.E.M.S
 
The evolution of S.E.M.S The Spindle Extraction Manipulation System. The idea of trying to defeat a combination lock through the spindle hole is not a new one. HPC have been marketing spindle hole defeat tools for over twenty years. Whilst difficult to use I suspect, due to their relative cheap cost, that most professional safe tech’s have a set just for the sake of ‘you never know when they may come in handy’. Many of you will of heard me say this before. John Falle of Falle Safe Securities, Jersey, Channel Islands U.K. is a genius. He has a proven track record of innovative design for nondestructive lock opening tools that is unparalleled in our industry. About 15 years ago John and I, had a discussion regarding the merits of a tool that would open a combination lock through the existing spindle hole in a safe container. At that time John felt sure he could design a tool that would achieve this in a simple and efficient manner. Over the years our business relation ship has  cente... read more
